Abstract: A vinyl resin composition is obtained by mixing the vinyl resin with plasticizer in combination with three surfactants, namely, a partial aliphatic glycerine ester, a partial aliphatic ester of sorbitan and a polyalkoxylated alkyl phenol to produce a composition which has excellent antifogging and antiblocking properties and is more readily sheeted in the film than compositions without these three surfactants.

Abstract: A laminate of a blend of 40 to 80 parts of polyvinyl chloride and 60 to 20 parts of a copolymer of butadiene acrylonitrile adhered to a substrate of polypropylene with a latex or solvent solution of a copolymer of vinylidene chloride and a second monomer of vinyl chloride or acrylonitrile can be formed as films which have excellent heat sealability.

Abstract: A packaging film composite and packaged articles therewith, said packaged articles include unvulcanized rubber compounding ingredients for unvulcanized rubber and compounding ingredients for thermoplastic polymers. Said packaged film composite is comprised of (1) an unvulcanized elastomeric block copolymer, (2) an anti-block agent selected from (A) stearyl erucamide and behenamide, (B) oleyl palmitamide and behenamide and (C) stearyl erucamide, oleyl palmitamide and behenamide, and, preferably, (3) a thermoplastic resin characterized by being soluble in styrene. The invention further relates to a method of preparing said packaged articles and to compounded high unsaturation rubber and compounded thermoplastic polymers prepared by mixing a package of compounding agents therewith packaged with the film composite of this invention.

Abstract: An extrudable compounded polyvinyl chloride and a method for its preparation which comprises a free-flowing particulate mixture of polyvinyl chloride, selected plasticizer, silica pigment, selected heat stabilizer, selected chelator, lubricant, selected surfactant and selected slip-antiblock agent. The compounded polyvinyl chloride uniquely has, as an extruded film, anti-moisture fogging and oxygen transmissive properties suitable for packaging meat, yet can be used in high speed packaging machines.
